Cornishsimon is correct however according to Flightradar24 G-CIXV operated a LCY to Faro flight under an Eastern flight number yesterday morning, presumably as a charter as it later positioned Faro -Birmingham.
Interestingly E170 G-CIXW has positioned to Isle of Man this evening and is scheduled to operate two return IOM-LCY rotations on behalf of BA Cityflyer tomorrow morning in place of the usual Saab. Presumably this is planned to provide additional capacity.
